I once had an interesting discussion with a gentleman who may (or may not) have been an American spy in Rumania several years before the "fall". We discussed a TV show in which a superspy entered Rumania by floating down the Danube in an inflatable rubber suit(!) "into the heart of Bucharest." My friend thought this was interesting, since Bucharest is around 80km from the river. Apparently, the show's writer got it confused with Budapest.
He laughed at the idea of a balding, middle aged, somewhat overweight man floating down the river, and told me that the last time he had been in Rumania, he had flown in on an Aeroflot flight from Moscow. His cover was as an employee of the Ministry of Agriculture, back from studying Soviet collective farms. Official orders, ID, etc. all in perfect order. The language was no problem as he is a native Rumanian (did you think we hired Americans?). He also laughed at the idea of carrying a gun and said he had no knowledge of weapons or the martial arts.
He was a little concerned about customs, so he told the customs guards that he had brought along a little something for good servants of the state. He told them to do their duty, open his suitcase, and "confiscate" some illegal stuff, which happened to be two bottles of the very best Russian vodka. Sure enough, they found the "contraband", took it (in the interests of the state, of course) had a good laugh and, to his relief, did not find the high speed radio transmitter in the bottom of the suitcase.
Or at least that is what might (or might not) have happened.
